Hi,
There is no difference.
All methods of an interface are abstract and public by default.
So, you could even type:
interface Test {
void test();
}
and it will have the same exact effect as your examples.

If you're interested in knowing whether the action is being called as a

For a forward it is javax.servlet.forward.request_uri and for an
